To all whom it may concern:

Be it nown that I, JOHN I. ARBOGAST, a

vcitizen of the United' States of America, re-

siding at S. S.v Pittsburg, in the-county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvementsl in Machines for Producing Hollow Glass Articles, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a machine for producing hollow glass articles, and the object o f my invention is to provide in a manner as hereinafter set forth a machine by which the cost of producing hollow glass ware can be. reduced to a minimum and more uniform ware or articles olff tained.

Another object of this invention lis to provide a novel machine for producing hollow'glass articles by which theuidcapacity of hollow articles, as bottles, can be more accurately regulated.

A further object of the invention is to provide a. machine for making hollow glass articles more expeditiously and with a greater degree of certainty as to the character of the articles produced than by machines heretofore devised and manually or automatically operated.

Reference will now be had to the drawings forming a partof this specification, wherein Figure 1 is an enlarged vertical sectional view of a presser plunger adapted to form part of the machine, Fig. 2 is a vertical cross sectional view of the `mold table or carrier, Fig. 3 is a plan of the same, and Fig.' 4 is a vertical sectional view of the blank .mold within a blow mold.

rIhe machine is shown illustrated in connection with a suction pipe and head for conveyingr a batch of glass to the molds forming' elements of the machine and the said suction pipe and head is conventionally shown and the pipe is indicated by the reference character 22 and theisuctionhead by the reference character 26.

rlhe floor orfoundation upon which the machine is erected is provided witha counter-sunk base plate 39 having a.y central bearing 40 and a post 41. The upper face of the bearing 40 is provided with an annular ball race 42 forvanti-friction balls 43, and revolubly' mounted upon these'xballs is the carrier or table, comprising a circular horizontally disposed platform 44 and a plurality of super-imposed Kcircular plat.

forms 45, all of said supenimposed platforms being' in the same horizontal plane and equally spaced apart. The super-imposed platforms, which are preferably four in number, are supported by posts 46 and by vertically extending cylindrical shells 47 disposed centrally with respect to the platforms 44 and 45 and carried by the platform 44. The shells 47 are provided with diametrically disposed vertical slots 48 and protruding through said slots are pins 49, carried bythe side walls of blank molds 50 located in said shells, the pins 49 being arranged adjacent to the lower end of each mold. The upper end of each mold 50 is provided wit-h a cavity 5l adapted to receive a quantity of molten glass 52 from thefsuction head 26. The blank molds v50 are adapted to be raised and lowered in the shells 47, and to accomplish such a. movement of the blank molds, I utilize actuators, each comprising` spaced vertical members 53 disposed upon opposite sides of the shells 47 between the platform 44 and the superimposed platforms 45. The spaced members 53 are connected at their inner and outer ends by means of cross bars 54, and said members are adapted for a slidable movement between the platforms 44 .and 45. The actuators are guided in their slidable movement by means of radially disthe outer bars 54 of said actuators, power being applied to these handles in effecting a movement of the actuators and the practical operation of the invention. The actuators may be operated manually by grasping the handle 56 or by means ofy any suitable power applied thereto, as found most suitable in the use of the invention. lIhe members 53 are provided with inclined slots 57 constituting ways or ,guides for the extremities of the pins 49 which protrude through the vertical slots 48 of the shells 47. The actuators are adapted for a reciprocal movement in edecting the shifting of the blank molds. 50, and when the'molds are in their normal position, the pins 49 are at thelower ends of the slots 57. When a slidable or re lciprocal movement is imparted to the actuators by the operation of the handle56 or movement, each of Vmovement of the 'a post 63 at the side of the collar 59.

Vpieces 7 0B,

any other suitable power medium, the pins- 49 are caused to move upwardly along the inclined ways or slots 57 thus actuating the blank molds to impart a vertical movement theretb, said molds being guided in their vertical movement by the vertical slots t8 in the shells. 47. The aforesaid vertical blank molds is adapted to project the same upwardly through central openings 58 provided therefor in thevsuperimposed platforms 45, ing their upper edges surrounded by collars 59 formed integral with the platforms The outer edges of the 'collars 59 are beveled, as at 60 for a purpose that will presently appear. ln order to hold the blank molds at the limit of their upward the slots or guide ways 57 merge at their upper ends into -a horizontal seat G1, and the pins 49 rest in the seats 61 after the blank molds have been elevated. .The lower en'ds of the slots or guide ways 57 `also merge into horizontal seat 62 adapted to receive the pins 4:9 and retain the blank molds in a lowered position.

Upon each of the super-imposed plat-- forms 45 is mounted a sectional bottom plate, a sectional blow mold and a sectional neckring, these elements being arranged one above the other and pivotally connected to The bottom plate whichV rests uponthe platform 45 comprises two sections 64, each provided with a handle 65 and with a semi-circular recess G6 adapted to provide clearanceefor thecollar 59 when the sectionsof the bottom plate are closed over the collar 59 and the opening 58. The recess 66 of each bottom plate is so shaped as to inter-lock with `the beveled edges of the collar 59 when in a closed position. The upper faces of the mold plate sections 6l are recessed, as at- 67 to form a shaping cavity adapted to properly shape the bottom of a blank blown upon said mold plate. This shaping cavity is best. shown in the right hand side of Fig. 2. Adapted to swing on to the mold plate are the sections 68 of a blow mold, said sections having the confronting faces thereof provided with molding recesses 69 adapted to shape the blank blown. in said blow mold. Adapted to swing over the blow mold are the sections 70 of a neck ring, these sections having the confronting faces thereof recessed, as at 71 to receive the upper end of the gathered glass 52 and hold the same during the pressing or blowing operation. Of course recesses 67, 69 and 7l will be shaped to conform to the hollow glass article to be produced by the machine. The sections 7 0 of the neck ring are loosely mounted upon the postV 63, whereby -said sections can be raised and, lowered, such movement being necessary in order that depending breastthese openings havforming head 77 withinthe housing -coupling piece 84 adapted to be carried by the sections 70 can.

be inserted and withdrawn from the blow mold.

The platform la is provided with a central depending circular flange 72 adapted to surround the bearing 40 and prevent accidental displacement of the platform all relatively to said bearing. The outer walls of the flange 72 are provided with ratchet teeth 7 3, preferably four in number, adapted yto coperate with the. mechanism employed for intermittently moving the carrier or table.

i The upper vend of the post Ll1 is provided with two fixed radially disposed arms 74: and 75 disposed at right angles to one another. The outer end of the arm 7a is provided with a cylindrical housing 76l for the upper end of a presser plunger 77, the upper end of 'said plunger having a head 78 while. the lower end thereof is p ovided with a 79. Encircling the plunger 7 6 lis a coiled retractis interposed between ing spring S0 which the lower end of head .78 to normally maintain the presser plunger in an elevated position. The plunger intermediate the ends thereof is provided with a suitable knob or handle 81, which can .be easily gripped when it 'is desired to manually lower the plunger 77.

aThe outer end with a housing82 for the upper end of a blow pipe nozzle 83. The nozzle 83 has the upper end thereof provided with a connected to a flexible air supply pipe 85. Arranged within the housing 82 and encircling the nozzle 83 between the coupling piece 84 and the bottom of said housing is a coiled retracting spring 86 adapted to normally maintain the blow pipe in an elevated position. The lower end ofthe nozzle is provided with a collar 87 adapted to limit the movement of the lower end of said pipe when entering' a pre-pressed blank to blow the blank to a finished form. The nozzle intermediate the ends thereof is .enlarged to provide a hand grip 88. Suitable power otherv than hand power can be employed for lowering the plunger 77 and the nozzle 93.

The mechanism for ,shifting the platform 44. is as follows: A' solenoid 99 is located adjacent to the base plate 39, and the core 100 thereof is provided with a spring pressed pawl 101 adapted to engage the ratchet teeth 73 and move the platform 4e. The pawl 101 is guided in its forward movement -by a rib 102, and said pawl and the core' are restored to their normal position by a retractile spring 103. ,l

With the bot-tom plate open, the sectional blow mold. v closed, the blank mold raised inv the blow mold, and the neck ring in an open position, as shownat station A of Fig. 3, the

`.gathering of glass is deposited in the blank the housing 76 and the of the arm 7 5' is provided roo iro

isb

mold. neef the operators located at either the station B, C or D then causes the solenoid 99 to be energized whereby the platform 44 will be revolved a quarter of a revolution,` thus placing the gathered glass at the station B. The operator at this station closes the neck ring and then 'lowers the armsA 74tand 75, whereby the presser plunger 77, carried by the arm 74- will be lowered, causing the forming head 79 to enter the gathered glass within the blank mold V50 and provide a blank with a cavity 110. When the forming head 79 enters the gathered glass, a portion of the glass is forced upwardly into the neck ring, which holds the pre-pressed blank while further operations are performed. The operator at station B then withdraws the blank mold from the blow mold. The platform et is revolved another quarter of a revolution to place the pre-pressed blank at the station C. The operator at this station closes` the bottom plate and lowers the arms 74 and 75, whereby the nozzle 83 will enter the cavity ll() and the supply of air passing through the nozzle is adapted to blow the pre-pressed blank to a shape confined within the blow mold. After the pre-pressed blank has been. blown, the operator can thenopen the neck ring. The platform is then vrevolif'ed another quarter of a revolution and the blown article is transferred to station D, where the operator located at this station opens'the neck ring, if` it has not been previously performed -at station C, opens the blow mold, rt'wmoves the blown article, opens the bottom plate, closes the blow mold, and then elevates the blank mold into the blow mold, whereby when the table is revolved another quarter of a revolution, the blow mold (.:ontaining the blank mold will be in position at station A to receive a' gathering of glass.

FromA the foregoing it will be observed that the lowering of the arms 74 and 7o can be timed, whereby when a blank is being pre-pressed at the station l a pre-pressed' blank can be blown at the station C. Furthermore it is apparent that these steps taken in connection with the carrier or mold table that simultaneously with the depositing of a suitable gathering of glass in the blank mold at station A, vthat the above mentioned operations can be performed and the operation of re-arranging the'molds and removing the article performed at station D.
